Question

why cell membrane is semi semipermeable in nature
​

Answer 1

Answer:

Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.

Answer 2

Explanation:

So since it only allows small and non polar molecules to pass in, it is described as partially permeable or semi-permeable. Those ions and molecules restricted by the phospholipids pass in and out of the cell via membrane proteins
